Convenient price for a 4 channel device, the device has good-manufactured remote control unit that's easy to hold in a pocket or a key chain. No manual and no explanation find on the internet to change Between M,S and L function. I'am afraid this won't work. No user manual supplied (not that I needed one, but someone might). - Regarding the product itself - no cons so far. Consider if you need an control with Latch, Momentary and Toggle. If you looking for something like this I dont think you can find any better for this price. A bargain! Read more

great price, really small size, and light weight black box with receiver is really small, then is really hard to attach huge cables to the relays and no manual supplied it switches relay on, when you press the button and when released it opens relay, I need to do some soldering or IO programming...great price, really small size, and light weight black box with receiver is really small, then is really hard to attach huge cables to the relays and no manual supplied it switches relay on, when you press the button and when released it opens relay, I need to do some soldering or IO programming to do what I want, but it is a really usefull device If you looking for something like this I dont think you can find any better for this price.

Good quality, especially compared to price.

Range seems to be good, in my application distance between TX and RX is ~10m, a couple of walls between those, and I don't have to extract the antenna on the remote at all. Easy to use and to install. Versatile, can be connected to open/close circuit, whichever is needed. No user manual supplied (not that I needed one, but someone might). What comes to the product itself - no cons so far. I personally would like more, if the transmitter was just plain black for example. The wood-look-alike is not the best choice. Does the job. Good value for the money. Read more

Good range from the remote trigger The unit comes witout any instructions. It seems quite simple to operate so this is not a real problem, if you are reasonably experienced at wiring things together It only comes with one remote trigger, it would be good to have the option to have a second one. There is very little space inside the box. I've wired up two channels of the four and struggled to get the box screwed back together with the PCB inside. If you wire up all four, it might be very difficult indeed I would not recommend this to be used for remote door opener or engine start circuits as there are no details of what encryption there is on the signal. It might be easy to compromise The switch is only a momentary latch - if you want to use it to switch something on and for the item to stay on, then you need to add additional circuitry. The relays on the board are rated at 15A so it might be possible to use it for more than the 5A that the switch is rated at, but the tracks in the circuit board are quite small so it might not be wise! Works really well in the car that I have installed it in. I'd certainly use it again if I had a similar requirement Read more

(receiver also seem to work with 9v battery as a power supply) I'm not actually fan of relay schemes, and hope this won't affect reliability in wide variety of temperatures (-30/+30?) and moisture. it would be quite nice to have such transmitter - receiver kits based on non-relay schemes, so as to minimize the size of receiver. Also availability of cheap 1 channel receivers for present RC would be perfect. I appreciate the variety of such devices available for purchase, and look forward for any fresh RC samples to test.

- Assembling of the PCB looks nice.
- There is a diodes to protect transistors-keys, which control relays.
- Change of address like SKU: 3072 (see HOW TO?? thread)
- Choice of operating modes of the relay (by jumper switch)
- Change
- Sensing distance corresponds declared in to the specifications...- Assembling of the PCB looks nice.

- Very nice price - No manual in box, well, to hell with him :) I want to buy 4 more remote!!!!!!!!!!

Hard to find
Cheap
Customizable
Low power consumption (ma standby
4 relays that each one can have two outputs (one inverted)
Relay can be programmed to toggle or not toggle
Each relay is mapped to its own button on the remote Not any yet
Didnt get any instruction.
NC means inverted relay output....Hard to find

NC means inverted relay output. Ive been looking for something as this for a long time. Im using it as a remote control for my autopilot on my boat. Just connect the relays output to the buttons om the autopilot If you looking for something like this I dont think you can find any better for this price. A bargain! Read more
